This is an album comprised mostly of unused material that was initially written for Mass Effect 2, with Track 1 being the notable exception. Tracks marked "Unused" are tracks that were completed but never actually submitted to BioWare for use in the game. Tracks marked "draft" were just ideas for possible use in the game that were either initially rejected, or else just set aside to pursue another idea instead.

Shepard of the Galaxy is an unofficial musical tribute to both the score and story of BioWare's amazing Mass Effect series. Special thanks go out to the original composers of the series, most particularly Jack Wall, Sam Hulick, and Clint Mansell for writing such inspiring music, and to the directors and crew at BioWare for creating such captivating and moving game experiences.
